NON-FREEZING ,HYDRAN'T.

SPECIFICATION formingpart of Letters Patent No. 287,815, dated. November 6,1883.

Application filed January 5, 1883. 7 (No model.)

To all whom it may concern Be it known thatI, HENRY FLETTER, a citizen of the United States, residing at Kalamazoo, county of Kalamazoo, State of jMichigan, have invented a new and useful N on- Freezing Hydrant, of which the following isa specification.

The object-of my invention is to effect certain improvements in hydrants and hydrantva1ves,to facilitate theoperation and, prevent freezing. a

A construction embodying my improvements consists in a cylindrical valve chamber or shell having three ports or ways leading therefrom, provided with a cylindrical valve or stop-cock having a circular passage or way through it at such a location that by turning the valve a continuous way or passage may be temporarily established between the supply and hydrant ports, while the waste-port is closed, or between the hydrant and waste ports, while the supply-port is closed. This construction is designated as a two way valve in a three-way chamber. A further construction consists in a device for operating the valve in a hydrant used in a building.

In the drawings forming a partof this specification, Figure 1 shows a side elevation of an out-door hydrant with the valve in use; Fig. 2, a side elevation of ani11-doorhydrant,showing mynew device for operating; Fig. 3, avertical section of the upper end of the hydrant in Fig. 2; Fig. 4., a horizontal section on line 1 1 in Figs. 1 and 6, showing a top view of the portion below said line; Fig. 5, a perspective of the valve or stop-cock in Figs. 1, 4, and 6; and Fig. 6 is a side elevation of the valvechamber enlarged from thatin Fig. 1.

R is the valve chamber or shell, having a supplyport, a, a hydrant-port, a, and a waste-port, a. y

S is the valve, having the circular passage or way y, Fig. 5. In Fig. 4 the valve is in a' position that a continuous passage is established between the supply and hydrant ports, while the waste port is closed. When the Valve is in this position,- the water passes up the hydrant-pipe. By turning the valve S until a passage is established between the hydrant-port and the waste-port, and the sup? ply-port is closed, as indicated by dotted lines In Fig. 2, B B illustrate a hydrant located indoors, having faucets u u in different stories of the building. In this figure the valve-chamber R, with its valve S, are located in a horizontal position.

e is a weighted valve-lever, secured to the end of the valve S.

c0 is a rope secured to the end of the weighted lever e, thence passing around pulley 02, extending up through the floors A A of the different stories, and is secured to the air valve lever O. This lever is secured to an airvalve,'J, made like the water-valve S, .and located in shell or chamber m at the top of the hydrant B. The chamber m has two air-ports, one leading. into it and another leading from it into the hydrant. WVhen air-valve J is 10- 7 cated as in Fig. 3, a continuous passage is established between the two air-ports. Rope c is'secured to one endof lever O and passes downinto the different stories.

1) o are rings to'take hold of. By this ar- .rangement the air-ports are opened when the water-supply port is closed and thewaste-port is opened, and vice versa. The object of admitting air into the hydrant above the water is of course to. facilitate the downward flow of 8 the water out of the waste-port before it can congeal by the cold.

By this device water may be admitted and shut off in the chamber R in the basement of the building by any one in the different stories at will. Pulling down on rope c admits the water, the valve S being then as in Fig. 4, and when rope 0 is released the weight 10 turns the valve back and opens the waste-port.

P Din Fig. 2 are thesupply and waste pipes, connecting with ports a a. Weight w is adjustable on lever e by means of a set-screw.

Having thus described my invention, what I claim as new is, I 1
